The cause of death for Becca Tobin‘s boyfriend Matt Bendik has not been determined after an autopsy was performed.

More studies will need to be performed, “as is the usual procedure in evaluating a sudden, unexpected death,” a spokesperson for the Philadelphia Medical Examiner’s Office told Philly.com about the 28-year-old Glee actress’ late boyfriend. Stayed tuned for more details.

The 28-year-old actress, who played Kitty on Glee for the past two seasons, was accompanying Matt, a 35-year-old nightclub owner, on a business trip, according to TMZ.

Becca and Matt had a fun night on the town with friends on Wednesday and returned to their hotel together that evening. His body was found the next day by a hotel maid and it’s unclear where Becca was at the time.

No details on Matt‘s death are known at this time, but the Philadelphia Medical Examiner has confirmed that his body was found at the hotel.

We send our thoughts and condolences to Becca and all of Matt‘s loved ones during this very difficult time.
